Abstract
An intrauterine balloon catheter for inhibiting formation of intrauterine adhesions in a mammalian uterus comprising balloon and a sheath, wherein the balloon is at least partially attached to the inner surface of the sheath and wherein the balloon and sheath, when the balloon is inflated, conform to the size and shape of the uterus and contact the wall of the uterus. The catheter further comprises a pressure control lock, clipping unit and one or more therapeutic agents which are therapeutically effective in inhibiting intrauterine adhesion formation.

An apparatus for preventing intrauterine adhesions, the apparatus comprising:
- an intrauterine balloon catheter, comprising:
- a flexible sheath having an inner lumen comprising at least one longitudinal perforation or slotted section for permitting the sheath to split into opposing longitudinal pieces from a compact configuration;
- and
- an inflatable balloon disposed within the sheath inner lumen and coupled to a surface of the sheath inner lumen, the balloon having an inflated configuration in which the balloon expands the opposing longitudinal pieces from the compact configuration to conform to a shape of an obstetrical site;
- an insufflation tube coupled to the balloon for providing a distending medium to inflate the balloon to the inflated configuration;
- and
- a pressure lock mechanism coupled to a proximal end portion of the catheter and in fluid communication with the balloon for maintaining a constant pressure of the balloon until bleeding reduces significantly or stops.
A method for minimizing or preventing intrauterine adhesions, the method comprising:
- inserting an intrauterine balloon catheter into an obstetrical site of a patient in a compact configuration, the intrauterine balloon catheter comprising a flexible sheath and an inflatable balloon disposed within and coupled to an inner lumen of the sheath, the sheath comprising at least one longitudinal perforation or slotted section for permitting the sheath to split into opposing longitudinal pieces from a compact configuration;
- expanding the balloon to an inflated configuration in which the balloon expands the opposing longitudinal pieces from the compact configuration to conform to the shape of the obstetrical site;
- and
- releasing the balloon catheter to reside within the obstetrical site.
